Setting 4: Frequency Detection 1
Output closes whenever the output frequency is equal to or below the value of the programmed Speed Agreement Level (L4-01). The Speed Agreement
Width (L4-02) is the hysteresis to Frequency Detection 1.
Status Description
Open Drive is stopped or the condition described below is not true
Closed Frequency Detection 1 > (+L4-01 greater than or equal to output frequency greater than or equal to -L4-01, L4-02)
Note: The terminal opens when the output for Frequency Detection 1 reaches the level set to L4-01. Frequency Detection 1 can also be used when the motor is rotating in reverse.

Setting 5: Frequency Detection 2
Output closes whenever the output frequency is equal to or above the value of the programmed Speed Agreement Level (L4-01). The Speed Agreement
Width (L4-02) is the hysteresis to Frequency Detection 2.
Status Description
Open Drive is stopped or the condition described below is not true
Closed Frequency Detection 1 > (+L4-01 greater than or equal to output frequency greater than or equal to -L4-01, L4-02)
No. Parameter Name Setting Range Default Page
L4-01 Frequency Detection Level 0.0 to 400.0 0.0 Hz −
L4-02 Frequency Detection Width 0.0 to 20.0 2.0 Hz −
Note: The output terminal set for Frequency Detection 2 will close when the output frequency falls below the level set to L4-01 minus the Speed Agree detection width set to L4-02.
Frequency Detection 2 can also be used when the motor is rotating in reverse.

Setting 6: Drive Ready
Output closes whenever the drive is not in a fault state and not being programmed. If b1-08 = 1: Enabled”, a drive that is in an active Run state that is also
being programmed will have the Drive Ready output closed.
Status Description
Open Processing: Drive is powering up, initializing parameter settings, dealing with a fault situation, or in the Programming Mode.
